What is BS EN 1626 - Valves for cryogenic service about?
BS EN 1626 is a technical specification that specifies the requirements for the design, manufacture, and testing of valves for cryogenic service, i.e., for operation with cryogenic fluids below - 10 °C as well as at ambient conditions to allow for start-up and run-down. BS EN 1626 specifies additional requirements for cryogenic service for the appropriate valve product standard.
BS EN 1626 applies to sizes up to DN 150 including vacuum jacketed cryogenic valves. BS EN 1626 is not applicable to safety valves and valves for liquefied natural gas (LNG). According to BS EN 1626, the valve is intended to be designed and tested to satisfy a pressure rating (PN or Class). Valves may then be selected with a PN or Class equal to or greater than the maximum allowable pressure (PS) of the equipment with which it is to be used.
Note: A cryogenic fluid (refrigerated liquefied gas) is a gas that is partially liquid because of its low temperature (including totally evaporated liquids and supercritical fluids).
Who is BS EN 1626 - Valves for cryogenic service for?
BS EN 1626 on valves for cryogenic service is useful for:
- Valves and cryogenic equipment manufacturers
- The oil and gas industry
- The water and steam industry
- The petrochemical industry
- The chemical industry
- Environmental testing
- Quality control personnel
Why should you use BS EN 1626 - Valves for cryogenic service?
A cryogenic valve is often designed to respond to high pressure by opening the valve, allowing gas or other media to flow freely through it. Cryogenic valves are designed to safely retain such gases and also work well during transit because they can operate at high and low pressures.
BS EN 1626 guidelines provide manufacturers with the terminology, requirements, and test methods for the quality assurance of valves for cryogenic service. To keep cryogenic gases or other mediums secure and safe, cryogenic valves are kept in a naturally closed condition. BS EN 1626 provides manufacturers with test methods for increased efficiency, durability, and quality management.
